Found a couple of Spanish Shawls mating last week off Santa Cruz Island in SoCal. Quite an unusual sight...

Wisnu, awesome! I'm in love with the first one. I have never seen one like that before!

@Wisnu - great pictures. I love the first one too - do you have an ID for it?

@Wisnu - great shots! The first one is a pleurobranch, a.k.a sidegill slug. This is probably Pleurobranchus forskalii, which can be this color or a maroon-type color. Great captures with the emperor shrimp!

I'm pretty sure it's Pleurobranchus mamillatus.

thanks all,
we saw few in secret bay - size approx. 1 cm
agree with Max, I think it's Pleurobranchus mamillatus,

i'm more interested on the pic no. 3 - not sure what they are doing; look like mating, but they are different species, on the right is Rsbecia tryoni.and Hypselodoris pulchella on the left
Several time I saw these nudies are trailing - but first time i found on that position

 

[Wisnu]

few more, still from Bali

Nudibranchs have their reproductive organs on their left side. To mate, they have to be facing opposite directions. These two were just eating side by side.
